To all ulhom may concern:

Be it known that we, FRANcoIs BERAUD,

residing at Lyon, and HENRI JANTON, residing at Villeurbanne, France,citizens of the French Republic, have invented certain new and usefulImprovements in Automatic Regulators for Use inWinding Fabrics, Threads,

' ing threads or yarns or Yarns, of which the following is aspecification. 1

.This invention relates to a new or improved automatic regulator for usein windand fabrics and which permits .of progressively reducing thespeed of the winding-roller proportionally to the increase in thediameter of the material wound in order to obtain a constant tensionfrom beginning to end of the operation.

The invention is represented in the annexed drawings, in which Figure lis a side view, and Fig. 2 an end view, of the regulator.

On a shaft A, suitably mounted in a frame I (not shown) is mounted adisk A,which transmits its movement to a friction-roller B, havinglongitudinal movement along a spindle C, but'rotating therewith, saidspindle communicating its movement at a reduced speed to another shaft Dby a train of toothed wheelgear C C C Said shaft D carries near its endop osite the toothed wheel-gear a worm E, meshing with a worm-wheel F,mounted on the axle F of the winding-roller G, and upon said aXle isalso mounted a cam H, having a projecting surface I, which at eachrotation of the axle F acts on and oscillates a lever J, pivoted at J,the movement of which.

P, which drives a worm-wheel Q, having a series of graduations servingas indications for the degree of reduction to be obtained.

. i .A handle R, mounted on the shaft N, al-

lows of regulating atthe start the speed necessary for the reduction.

The operation of the regulator is as follows:

, The friction-disk A, rotating at a constant speed, drives thefriction-roller B, which transmits its movement to the shaft N by meansof the reducing'wheel-gear C C C the worm E and worm-Wheel F, the cam H,

the coacting levers J and K, dog L, and the driving-wheel M, mounted onsaid shaft N. The nut or slide 0 is thus displaced and moves thefriction-roller B, the speed of' which is thus reduced according as itapproaches the center of the. disk A. This reduction of speed iscommunicated by the same parts to the winding-roller G, the angularspeed of which is reduced, the peripheral speed, however, remainingconstant whatever the diameter of the winding.

This controller is particularly adapted for meshed fabrics, such astulle or bobbin-net and permits of always having the same number ofmeshes in every direction from one end of the piece to the other. It isalso applicable to all kinds of fabrics and for winding threads oryarns, for example, in weft-winding machines. g i

What we claim as our invention, and desire to secure by Letters Patentof. the United States, is-

1. Regulating mechanism for use in winding comprising in combination adisk, a roller havin frictional contact therewith, awinding-r0 ler,means for transmitting movement from the friction-roller to thewinding-roller at a reduced speed, a screw-threaded shaft,

means for imparting intermittent rotation to same according to the speedof the windingroller and means operated by said screwthreaded shaft forcausing the friction-roller to move over the surface of the aforesaiddisk for the purpose set forth.

2. Regulating mechanism for use in winding comprising in combination adisk, a roller having frictional contact therewith, a shaft carryingsaid roller, a worm-shaft, speed-reducing gear between the latter andthe roller:

shaft, a windin -roller driven by said wormshaft,,a screw-t eaded shaftmeans for imparting intermittent rotation to same according to the speedof the winding-roller and means o erated by said screw-threaded shaftfor causmg the friction-roller to move over the surface of the aforesaiddisk for the purpose set forth.

3. Regulating mechanism for use in Winding comprising in combination adisk a roller having frictional contact therewith, a shaft I carryingsaid roller, a worm-shaft, speed-reacted on by said cam, a driving-Wheelon the screw-threaded shaft actuated by said oscillatory levers, andmeans operated by said screw-threaded shaft for causing thefrictionroller to move over the surface of the afore- IO said'disk forthe purpose set forth.
